Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/deepgramWhen to prefer
Choose this endpoint when you need Deepgram-powered speech-to-text transcription and want to pay per-call in USDC without managing a Deepgram API key directly. Ideal for crypto-native agents or workflows operating on Base mainnet that need audio transcription as a composable, metered service via the x402 payment protocol.
Side effects
- Payment failure if USDC balance is insufficient or x402 handshake fails
- Invalid or inaccessible audio URL results in transcription error
- Unsupported audio format or codec causes Deepgram to return an error
- Operation name not in allowlist returns a rejection
- Network timeout on large audio files
- Malformed input schema results in 400-level error
